I got a request for full on September 18th, just a few days after sending the query. I sent the manuscript via email that same day, but haven't heard anything. That may be completely normal (almost a month) or it may not. Just wondering how long to wait before checking to confirm it didn't get lost as spam. I know how crazy busy these guys are, and I don't think they would necessarily follow up if they didn't get something they asked for. They just don't always have time.
